Texas divides its groundwater into more than 100 districts, each with its own rules, fees, and permit requirements. Before you drill a water well anywhere in the state, you need to know whether a Groundwater Conservation District covers your land — and what that district requires.
Here is a plain-language breakdown of what GCDs are, how they work, and what they mean for property owners in North Texas and across the state.
What Is a Groundwater Conservation District?
A Groundwater Conservation District (GCD) is a local government entity authorized by the Texas Legislature to regulate groundwater production within a defined boundary. GCDs operate under Chapter 36 of the Texas Water Code and are governed by locally elected or appointed boards.
Their primary mission is to protect, preserve, and recharge groundwater resources — balancing current use against long-term aquifer health. In practical terms, that means setting rules on who can drill, how deep, how much water can be pumped, and how wells must be reported.
There are currently 98 active Groundwater Conservation Districts in Texas, covering roughly 73 percent of the state’s land area. Some counties have one GCD. Others fall under two or more overlapping districts. And some rural areas have no GCD coverage at all.
Why GCDs Exist: The Texas Groundwater Problem
Texas does not operate on the “first in time, first in right” water doctrine used in western states. Instead, Texas historically followed the Rule of Capture — landowners could pump as much groundwater as they wanted from beneath their property, regardless of the impact on neighbors’ wells.
As aquifer levels declined and conflicts multiplied, the Legislature began authorizing local GCDs starting in the 1950s. The goal was to give communities control over shared underground resources before those resources were gone.
Today, GCDs represent the primary legal mechanism for groundwater management in Texas. They do not replace private ownership rights entirely — Texans still own the groundwater beneath their land — but GCDs can regulate how and when that water is produced.
What GCDs Can Regulate
Under state law, GCDs have authority to:
- Require permits to drill new wells
- Set spacing rules between wells
- Limit production volumes on larger wells
- Require metering and annual water use reporting
- Charge fees for drilling permits and production
- Regulate well construction standards (depth, casing, grouting)
- Order well plugging when a well is abandoned
Most residential domestic wells — typically defined as pumping 25,000 gallons per day or less — are exempt from production limits under state law. But you may still need a drilling permit and must follow construction standards even for an exempt domestic well.
The rules vary significantly by district. What is required in the Parker County area may differ from the rules covering Hood County or Palo Pinto County. Always check with the specific GCD before drilling.
How to Find Out If Your Land Is in a GCD
The Texas Water Development Board (TWDB) maintains an interactive map at twdb.texas.gov that shows all GCD boundaries. You can search by county or address to identify which district, if any, covers a specific parcel.
You can also use our free GCD lookup tool to identify the district covering your property and get basic information on permit requirements for that area.
If your property falls outside any GCD, state rules and Texas Commission on Environmental Quality (TCEQ) regulations still apply, but you will not need a local district permit.
GCDs and the Well Permit Process
For most North Texas property owners, getting a permit from the local GCD is one of the first steps in a new well project. The process typically looks like this:
- Application: Submit a drilling permit application to the GCD, including property owner information, proposed well location, and intended use.
- Fee: Most districts charge a permit fee, typically in the range of $50 to $300 for a residential domestic well.
- Approval: The GCD reviews spacing requirements and any objections. Most residential permits are approved without a hearing.
- Drilling: A licensed Texas well driller completes construction per district and TCEQ standards.
- Completion report: The driller files a State Well Report (SDR) with the TWDB within 30 days of completion.
Total permitting time for a residential well in most GCDs runs one to three weeks if paperwork is in order. Some districts process permits faster; a few require board review meetings that can add time.

Major GCDs Covering the DFW Region
If you are buying land or drilling a well in North Texas, these are the districts most relevant to you:
Trinity Glen Rose Groundwater Conservation District
Covers Erath and Somervell counties. Regulates production from the Trinity and Glen Rose aquifer systems. Permit required for all new wells.
Hood County Groundwater Conservation District
Covers Hood County entirely. Regulates wells tapping the Trinity Aquifer, which is the primary water source for the Granbury and Lake Granbury area.
Barton Springs / Edwards Aquifer Conservation District
While primarily in the Austin-area region, this district demonstrates how protective GCDs can be for sensitive recharge zones. Relevant for buyers considering land south of the Metroplex.
Brazos Valley Groundwater Conservation District
Covers Grimes, Leon, Madison, and Robertson counties. Manages production from the Carrizo-Wilcox aquifer in that corridor.
Note: Several DFW-area counties, including Tarrant and Dallas, are largely served by municipal water systems and have limited GCD coverage. But rural tracts in those counties and adjacent areas often fall under district jurisdiction.
GCDs and Real Estate: What Buyers Need to Know
If you are buying land in Texas with an existing water well, the seller is required to disclose well information under TREC Form 61-0. Part of what you should investigate: is the well properly permitted under the local GCD?
An unpermitted well in a district that requires permits is a compliance problem that transfers with the property. Before closing on any rural Texas land with a well, verify:
- Whether a GCD covers the property
- Whether the well has a valid GCD permit on file
- Whether the well was drilled by a TCEQ-licensed driller
- Whether a State Well Report is on file with the TWDB

The Bottom Line on GCDs
Groundwater Conservation Districts are not obstacles — they are the framework that keeps Texas aquifers functioning for the long term. Knowing your district’s rules before you drill saves time, money, and compliance headaches.
For most residential well projects in North Texas, the GCD permit process is straightforward and adds only a few weeks to the timeline. The bigger variable is drilling depth and geology — and that is where local knowledge matters most.
